Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package’s install hook visibly validates and installs its own CLI binary, which is consistent with its purpose. The bundled native binary appears to include Sentry crash reporting, but the available analysis cannot establish whether it is opt-in or what data it sends, so I’m flagging a runtime telemetry concern. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 66.0% - **Started:** 2026-11-03T11:17:30.037Z - **Finished:** 2026-11-03T11:18:46.985Z - **Download time:** 4371 ms - **Static scan time:** 163 ms - **AI review time:** 72413 ms - **Total time:** 76948 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The bundled native CLI appears to include Sentry crash reporting, but its default behavior and payload could not be confirmed. - **Trigger:** Potentially during CLI runtime or crash handling; whether reporting runs by default is unresolved. - **Impact:** Crash diagnostics may be sent to Sentry; the included analysis does not establish what data is collected. - **Evidence paths:** .lpm-inspection-ZKW855/5-281eae29984b.txt, native/win32-x64/tm.exe - **Review source:** ai\_review - **Reviewed:** 2026-11-03T11:18:46.985Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The native binary analysis includes a Sentry ingestion endpoint and a \`TM\_CRASH\_REPORTS\` setting. - **Rationale:** The package’s install hook visibly validates and installs its own CLI binary, which is consistent with its purpose. The bundled native binary appears to include Sentry crash reporting, but the available analysis cannot establish whether it is opt-in or what data it sends, so I’m flagging a runtime telemetry concern. - **Files touched:** native/win32-x64/tm.exe, install.js, bin/tm.js - **Network endpoints:** o4512288884326400.ingest.us.sentry.io, api.teammesh.io, sync.teammesh.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 66.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The Windows x64 native binary analysis contains a Sentry ingestion URL and the \`TM\_CRASH\_REPORTS\` setting., The native binary analysis also contains TeamMesh API and sync service URLs, consistent with the CLI’s stated purpose., The package routes the \`tm\` command through a platform-specific native binary., The postinstall hook runs the staged binary with \`--version\` before replacing the JavaScript shim. - **Evidence against:** The postinstall hook is conditional on platform and npm, and its visible actions are copying, validating, and replacing the CLI shim., The available native analysis does not establish whether crash reporting is enabled by default or what data it sends. ## Affected versions and remediation This report applies to teammesh@0.41.0. - Review the evidence and your use of teammesh@0.41.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
